All clutter dependencies seem to be installed:
apt list --installed | grep -i clutter

Perhaps you are missing some bindings? I also have these installed:

gir1.2-clutter-1.0
gir1.2-clutter-gst-3.0
gir1.2-gtkclutter-1.0

@franglais125 I'm on 18.04 and had this same issue. Your suggestion fixed it. Just ran:

$ sudo apt install gir1.2-clutter-1.0 gir1.2-clutter-gst-3.0 gir1.2-gtkclutter-1.0

Only gir1.2-clutter-1.0 is needed. You do not need gir1.2-clutter-gst-3.0 or gir1.2-gtkclutter-1.0.
